Del. Code tit. 11 § 2526
Any person arrested or detained for the commission of a crime in a foreign jurisdiction, may, after the rights to demand requisition papers have been fully explained, waive requisition and consent to return to the jurisdiction in which the person is wanted. The waiver of requisition shall be in writing, and shall set forth that the person voluntarily waives requisition and that the person's rights have been fully explained and are understood, which shall be signed by the prisoner and 3 other witnesses in the prisoner's presence. The proper signing of such a waiver of requisition shall constitute ample authority for the sheriff, or other officer having the prisoner in custody, to deliver the prisoner to the duly authorized agent commissioned to receive the prisoner. The sheriff, or other officer having the prisoner in charge, before the officer surrenders the prisoner shall be satisfied that the agent is duly authorized and commissioned to receive the prisoner, and shall, unless the agent is a known peace officer, demand and retain the agent's warrant of authority, which the officer shall file and preserve together with the prisoner's waiver of requisition.
